title: A test of two brief measures of grandiose narcissism: the narcissistic personality inventory-13 and the narcissistic personality inventory-16.
abstract: The most widely used measure of trait narcissism is the Narcissistic Personality Inventory (NPI), which can provide both total and subscale scores. However, with a length of 40 items, this measure may not be ideal in settings in which time or participant attention may limit the types of measures that can be administered. In response, Ames, Rose, and Anderson (2006) created the NPI-16, which provides a shorter, unidimensional measure of the construct. In the present research, we examine the reliability and validity of the NPI-16 in conjunction with a new short measure of narcissism, the NPI-13, which provides both a total score and 3 subscale scores (Leadership/Authority; Grandiose Exhibitionism; Entitlement/Exploitativeness). Across 2 studies, we demonstrate that both short measures manifest good convergent and discriminant validity and adequate overall reliability. The NPI-13 may be favored over the NPI-16 because it allows for the extraction of 3 subscales, consistent with the use of its parent measure.
